To all whom 'it may concern:

Be it known that we, WILLIAM F. SERVICE and WILBUR J. EMLEY, citizens of the United States, and residents of Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and use. ful Improvements in Scouring, Grinding, and Polishing Machines, of which the following is a specification.

This inventionrelates to scouring, grinding, painting and polishing machines and its object is to provide means for driving a.

spindle carrying a brush which at the same time shall afford means for supplying the brush with the necessary water or polishing and scouring solution to a greater or less degree, the whole to be conveniently and compactly carried about for operation at any desired point and driven by a fluid under com ression as will be more fully eX- lained in the followingv specification, set orth in the claims and illustrated in the drawings, where:

Figure 1 is a side elevation of the device. Fig. 2 is a vertical sectional view. Fig. 3 is a side view of the motor casing. Fig. 4 is a plan view of same. Fig. 5 is a View of the opposite side of Fig. 3. Fig. 6 is an edge View of the casing. Fig. 7 is a side View of part of the motor wheel. Fig. 8 is an edge view of same partly in section.

The device is adapted to carry and operate a brush for scouring or a wheel for polishing and which is held securely on the shaft 10 by screwing it thereon and locking it by means of the nut 11 or in any other manner that may be found desirable. The shaft 10 is hollow and is journaled in the sleeves 12 of the two part casing 13 being lubricated by means of the oil cups 14 and keyed to the shaft is a motorwheel 15 preferably made in two parts and having near its outer edge the V-shaped openings 16 passing from one side of the wheel to the other and separated by the walls 17. The center of the wheel is formed as a web 18 and its hub 19 receives the key 2O which secures it to the shaft 10 and has at each side the packing 20.

The casing 13 has an inlet 21 for the motive Huid which is supplied throu h the pipe 22 carried at the outer end of t e hose 23 and the compressed air or other i'luid passes through the ports 24 and strikes the walls 17 acting upon the inclined faces so as to force the wheel around and as the air passes through the openings 16 and reaches the other side of the casing it leaves the port 25 of Fig. 5 moving through the by-pass 26 and renters the ports 27 again acting upon the faces of the walls 17 and crossing .to the front side of the casing where-it leaves the 'openings 16 through the port 28 and enters thc by-pass 29, leaving it through the ports 30 to again act upon the walls of the openings and pass to the rear side of the casing where it eaves the exhaust port 31.

While the force of the air decreases itwill be seen that the sizes of the ports by which it enters and leaves the openings increase 1n order to equalize the power of same and have its edect at all of the ports about the same.

The supply of air is regulated by means of a sleeve 32 carried by the coupling 33 which has the by-pass 34 connecting the openings 35 but as the sleeve is turned the connection may be made smaller or entirely closed cutting olf the air supply. The rotation of the sleeve is limited by pins 32 playing in slots 33.

While the shaft and brush are rotating the liquid necessary for the scrubbing or scouring is supplied from a tank 36 attached to the pipe and may be of any suitable size or length. The supply pipe 37 collects the liquid from the bottom of the tank and it is fed by means of the air blast issuing from the jet 38 connected with the pipe 22 and having a supply regulating cock 39. The air blast discharges into a pipe 40 carrying with it the liquid from the tank 36 which it carries through the hollow spindle and out of same at the center of the brush. The pipe 40 is connected with the supply pipe 37 by a suitable aii' tight coupling 41 and with the rotating shaft 10 by the sleeve 42 which is locked to the sleeve 12 by the nut 43.

This apparatus combines a scourer or rotating brush or grinder, means for rotating same and a blast for supplying water all4 carried at the end ofa flexible hose so that the device may be carried to any point and the scouring, polishing and cleaning be done about a room or apartment or in connection with wagons, cars and simllar articles, the
